"After the first few months of the new pontificate, the general impression is that no one within the Church is seriously criticizing the central theses - philosophical and theological - of Benedict XVI's preaching. But that's not the way it is. One Catholic philosopher has disputed one of the main points of Joseph Ratzinger's thought: the one dealing with the natural law and relativism. The philosopher is Dario Antiseri, a professor of social sciences methodology at the Free International University of Social Studies in Rome."

The above comes from Sandro Magister, an Italian journalist. The full text can be found at http://www.chiesa.espressonline.it. Magister's article includes a translation of a major piece of Dario Antiseri's original journal article.
